## 1. 安装依赖
|
||
|
||
Apache APISIX 的运行环境需要 Nginx 和 etcd，
|
||
|
||
所以在安装前，请根据不同的操作系统来[安装依赖](install-dependencies.md)。
|
||
|
||
通过 Docker / Helm Chart 安装时可能已经包含了所需的 Nginx 和 etcd。
|
||
请参照各自对应的文档。
|
||
|
||
## 2. 安装 Apache APISIX
|
||
|
||
你可以通过源码包、Docker、Helm Chart 等多种方式来安装 Apache APISIX。
|
||
|
||
### 通过 RPM 包安装（CentOS 7）
|
||
|
||
```shell
|
||
sudo yum install -y https://github.com/apache/apisix/releases/download/2.7/apisix-2.7-0.x86_64.rpm
|
||
```
|
||
|
||
### 通过 Docker 安装
|
||
|
||
见 https://hub.docker.com/r/apache/apisix
|
||
|
||
### 通过 Helm Chart 安装
|
||
|
||
见 https://github.com/apache/apisix-helm-chart
|
||
|
||
### 通过源码包安装
|
||
|
||
你需要先下载 Apache Release 源码包：
|
||
|
||
```shell
|
||
$ mkdir apisix-2.7
|
||
$ wget https://downloads.apache.org/apisix/2.7/apache-apisix-2.7-src.tgz
|
||
$ tar zxvf apache-apisix-2.7-src.tgz -C apisix-2.7
|
||
```
|
||
|
||
安装运行时依赖的 Lua 库：
|
||
|
||
```
|
||
cd apisix-2.7
|
||
make deps
|
||
```
|
||
|
||
## 3. 管理（启动、关闭等）APISIX 服务
|
||
|
||
我们可以在 apisix 的目录下用 `make run` 命令来启动服务，或者用 `make stop` 方式关闭服务。
|
||
|
||
```shell
|
||
# init nginx config file and etcd
|
||
$ make init
|
||
|
||
# start APISIX server
|
||
$ make run
|
||
|
||
# stop APISIX server gracefully
|
||
$ make quit
|
||
|
||
# stop APISIX server immediately
|
||
$ make stop
|
||
|
||
# more actions find by `help`
|
||
$ make help
|
||
```
|
||
|
||
## 4. 运行测试案例
|
||
|
||
1. 先安装 perl 的包管理器 cpanminus
|
||
2. 然后通过 cpanm 来安装 test-nginx 的依赖：`sudo cpanm --notest Test::Nginx IPC::Run > build.log 2>&1 || (cat build.log && exit 1)`
|
||
3. 然后 clone 最新的源码：`git clone https://github.com/iresty/test-nginx.git`。注意使用我们 fork 出来的版本。
|
||
4. 通过 perl 的 `prove` 命令来加载 test-nginx 的库，并运行 `/t` 目录下的测试案例集：
|
||
* 追加当前目录到perl模块目录： `export PERL5LIB=.:$PERL5LIB`
|
||
* 直接运行：`make test`
|
||
* 指定 nginx 二进制路径：`TEST_NGINX_BINARY=/usr/local/bin/openresty prove -Itest-nginx/lib -r t`
|
||
* 部分测试需要依赖外部服务和修改系统配置。如果想要完整地构建测试环境，可以参考 `ci/linux_openresty_common_runner.sh`。
|
||
|
||
### 疑难排解测试
|
||
|
||
**配置 Nginx 路径**
|
||
|
||
如果遇到问题 `Error unknown directive "lua_package_path" in /API_ASPIX/apisix/t/servroot/conf/nginx.conf`
|
||
确保将openresty设置为默认的nginx并按如下所示导出路径。
|
||
|
||
* export PATH=/usr/local/openresty/nginx/sbin:$PATH
|
||
* Linux 默认安装路径：
|
||
* export PATH=/usr/local/openresty/nginx/sbin:$PATH
|
||
* OSx 通过homebrew默认安装路径：
|
||
* export PATH=/usr/local/opt/openresty/nginx/sbin:$PATH
|
||
|
||
**运行单个测试用例**
|
||
|
||
- 使用以下命令运行指定的测试用例：
|
||
- prove -Itest-nginx/lib -r t/plugin/openid-connect.t
|
||
|
||
## 5. 更新 Admin API 的 token ，保护 Apache APISIX
|
||
|
||
修改 `conf/config.yaml` 中的 `apisix.admin_key` 并重启服务。例如下面例子：
|
||
|
||
```yaml
|
||
apisix:
|
||
# ... ...
|
||
admin_key
|
||
-
|
||
name: "admin"
|
||
key: abcdefghabcdefgh
|
||
role: admin
|
||
```
|
||
|
||
当我们需要访问 Admin API 时，就可以使用上面记录的 key 作为 token 了。
|
||
|
||
```shell
|
||
$ curl http://127.0.0.1:9080/apisix/admin/routes?api_key=abcdefghabcdefgh -i
|
||
HTTP/1.1 200 OK
|
||
Date: Fri, 28 Feb 2020 07:48:04 GMT
|
||
Content-Type: text/plain
|
||
... ...
|
||
{"node":{...},"action":"get"}
|
||
|
||
$ curl http://127.0.0.1:9080/apisix/admin/routes?api_key=abcdefghabcdefgh-invalid -i
|
||
HTTP/1.1 401 Unauthorized
|
||
Date: Fri, 28 Feb 2020 08:17:58 GMT
|
||
Content-Type: text/html
|
||
... ...
|
||
{"node":{...},"action":"get"}
|
||
```
|
||
|
||
## 6. 为 APISIX 构建 OpenResty
|
||
|
||
有些功能需要你引入额外的 Nginx 模块到 OpenResty 当中。
|
||
如果你需要这些功能，你可以用[这个脚本](https://raw.githubusercontent.com/api7/apisix-build-tools/master/build-apisix-openresty.sh)
|
||
构建 OpenResty。
|
||
|
||
## 7. 为 APISIX 添加 systemd 配置文件
|
||
|
||
如果通过 rpm 包安装 APISIX，配置文件已经自动安装到位，你可以直接运行
|
||
|
||
```
|
||
$ systemctl start apisix
|
||
$ systemctl stop apisix
|
||
$ systemctl enable apisix
|
||
```
|
||
|
||
如果通过其他方法安装，可以参考[配置文件模板](https://github.com/api7/apisix-build-tools/blob/master/usr/lib/systemd/system/apisix.service)进行修改，并将其放置在 `/usr/lib/systemd/system/apisix.service`。
